D9 Large Dozers

The Cat® D9 Dozer is a versatile machine designed to be used in a variety of applications, such as ripping overburden, production dozing, stockpiling, winching, site maintenance, fleet support and reclamation. It can be equipped with a number of blade options to meet site-specific needs. A highly reliable and fully integrated Cat machine, the D9’s components work together to ensure top performance, high availability and long life. Features like the new stator clutch torque converter boost efficiency and reduce fuel usage, and a number of onboard technology solutions further increase efficiency and performance. These improvements — and more — make the D9 a dozer that delivers a lower overall cost per unit of material moved.

Features

PERFORMANCE & EFFICIENCY

  • The torque converter with stator clutch automatically frees up the stator when torque multiplication is not required under low load, resulting in higher drivetrain efficiency for reduced fuel consumption.
  • Bogie suspension allows the track to conform to ground conditions, delivering higher traction and less slippage.
  • Differential steering enables large loads, with fast and smooth maneuvering.

OPERATOR COMFORT

  • The cab is unparalleled, with enhanced ergonomics, a fully adjustable air suspension seat and automatic temperature control.
  • The suspended undercarriage absorbs impact and reduces shock loads transferred to the undercarriage by up to 50% for a smoother, more comfortable ride.
  • Low-effort electronic steering, ripper and dozer controls are easily accessible and provide sure, precise maneuvering.

SAFETY

  • The operator station offers an exceptional viewing area, with a tapered hood, notched fuel tank, and narrow ripper carriage to give the operator a clear line of sight to front and rear work areas.
  • The optional 360 Vision camera system and in-cab display further enhance visibility.
  • An optional powered ladder improves access and egress.
  • Ground-level access, forward-hinging cab door, retention pins on bottom guard and removed lift cylinder grease points provide a greater level of safety for service personnel.

PRODUCTIVITY

  • Differential steering provides a tight turning radius and maintains a high ground speed while turning.
  • The planetary powershift transmission controls permit smooth speed and direction changes with Advanced Productivity Electronic Control System (APECS).
  • The in-cab touchscreen Information Display is larger, faster, and more powerful with increased memory and intuitive menu structure.
  • The optional Work Monitor screen collects machine data and provides real-time feedback on machine performance to optimize productivity.
  • The Dual Tilt option allows the operator to optimize blade pitch angle, improving load control and making it possible to carry material instead of only pushing it.

VERSATILITY

  • The D9 is versatile enough for a variety of applications and is ideal for use in heavy construction, quarries, landfills, stockpiles, forestry and mine sites.
  • The powerful Cat C18 Engine is available in U.S. EPA Tier 2, U.S. EPA Tier 3, U.S. EPA Tier 4 Final and EU Stage V configurations.
  • The fully suspended undercarriage provides more ground contact, leading to less slippage and more overall productivity in all applications.
  • Continuous power to both tracks provides smooth turning control and excellent maneuverability in every application, all while keeping ground speed high.
